（1） Application scenarios
1. Drinking water supply in coastal cities
2. Domestic water supply for island residents
3. Freshwater supply for offshore drilling platforms
4. Pre treatment of cooling water for thermal/nuclear power plants

（2） Membrane technology solution
High pressure reverse osmosis: single membrane water production of 12m ³/h (TDS 55000mg/L)
Energy recovery system: energy consumption per ton of water ≤ 3.5kWh
● Preprocessing: Immersion ultrafiltration (SDI ≤ 2)

（3） Technical advantages
Water production cost is 4.5-6 yuan/ton (50000 tons/day scale)
● Suitable for high hardness and high organic matter seawater
The stable operation cycle of the system is ≥ 3 years

（4） Research and Development Progress
The seawater desalination special membrane developed by Jinyu Membrane Technology has a desalination rate of 99.85% and a 5-fold increase in chlorine resistance. It has completed a pilot test of 10000 tons.
